PIN DESCRIPTION
NAME REF50xxI, REF50xxA REF50xxE
DNC 1, 8 8 Do not connect
EN - 1 Device enable control. Low level input disables the reference output and device enters shutdown mode. Device can be enabled by driving voltage > 1.6V or leaving the EN pin floating.
VIN 2 2 Input supply voltage
TEMP 3 3 Temperature monitoring pin. Provides a temperature-dependent output voltage
GND 4 4 Ground
TRIM/NR 5 - Output adjustment or noise reduction pin
NR - 5 Noise reduction pin
VOUT 6 6 Reference voltage output
NC 7 No internal connection
NC 7 Leave it floating or connect it to GND
